Not possible for a solo user until next few years.
I prefer random search. I am using RTX3060 and Keyhunt-Cuda in a random mode with an helper app. I am using 36 bit search with 9 random prefix. Link contains the ranges I have already scanned, it may not be useful if someone searching with less prefix.

You know how it goes, share too many details and in 2 minutes someone calls you a liar anyway 😉
Let’s just say it took time, decent firepower, and good software. If you know, you know.


liar or no liar you wrote you been working on puzzle 73 for months and scanned EVERYTHING from 10... to 14... witch i think is bigger than puzzle 71 range so .... no need to continue

That’s not true. I’ve been working on Puzzle 73 for months and have scanned everything up to prefix 14 from 1000000000000000000 to 14fffffffffffffffff. Higher puzzles like 71+ are absolutely being searched, even if they haven’t been solved yet.

lol i start searching today,using 4 Nvidia L4 each scanning at 335 m/k x to 312 m/k x sec is all about lucky?
But i believe the key is around 7............  why because Puzzle 70 was done in 2019-06-09 and since then nobody have find the key for 71 how many people have being scanning for key 71 since 2019-06-09 so must be around 6....... or 7............  what do you guys think?

hey, guys, did you know that keyhunt switch -R is not really working?

-b 135 -R

you think that it will start 135bit range from random place? fsck, no, it always starts from beginning of range.

sooo much wasted resources.... alberto is rediska

yeah, i mean has someone been able to collect the 32 BTC or not yet ?

I think I completed the puzzle but its suddenly gone. When I broadcasted it omg i work my ass of to get it even the time changed!

I don't understand what's the point of doing this.

I can solve your pubKey (or any other 75-bit public key for that matter) in at most 10 seconds from the moment it's grabbed from the mempool initial TX.

I based my statements on what you yourself said. The keyspace of Puzzle 71 is not particularly small either, but according to your claim, bots are capable of accessing the private key in a very short time simply by having the public key. Now, considering that Puzzle 135 has a larger keyspace—which I acknowledge—with the speed you attribute to these bots, don’t you think there has been ample time since the creation of these puzzles for the private key of Puzzle 135 to be discovered and the funds to be transferred? It appears that some of these claims may be misleading. Could it be that you are the same individual who took the Puzzle 69 funds from the person who found it?

a colleague got good speed with the 5090

True.
I have access to my monthly expenses in watts, but I confess that I don't even care about that anymore. In the winter I turn on everything I need to turn on to heat the house and in the summer everything to cool it down. My TV is also on 24 hours a day and I can't even sleep without it on. I think the TV helps me fall asleep. Well... that's how it is in my house... everything is on and I pay what I expect to pay... whether it's more or less than what I should pay, it's always within the usual amounts for many years   This is all due to using my 3060 for these puzzles. I already used it for trivial PC stuff, but now it's in full swing looking for wallet 71 maybe I'll get as lucky as I did with wallet 48

A few Cyclone updates: threads and public key skipping if it starts with K leading zeroes, because 71 partial hash generates with 1 max 2 leading zeroes  public key X ccordinates.

Don’t play that game with me, you’ll be the one losing. I know more than you think 

Just curios,

What hardware is everyone running for these puzzles? Whats the dream setup for you guys?

No, your original claim about 1% for competitors was totally incorrect.
Assume you have 10000 GPUs at most. For brute force with randomly chosen subranges, to get 99% of success for you, all other people on Earth who try to solve #69 must have only 100GPUs in total, which is ridiculous. Even if all of them have twice slower software than yours, it's 200GPUs in total. Again: all competitors who try to solve #69 must have only 200GPUs in total. It seems like you think that you are the only one who has more than 1GPU. So when you use wrong calculations, be ready for "1% wins".

We got robbed of Puzzle 69.

Hello, we are coming out to claim we are the group that solved puzzle 69.
We are a group consisting of 12 software developers in Asia with interest in cryptography. We have been scanning puzzle 66, 67, 68 and 69 since last year.

We have rented several GPUs online to use for the puzzles. Unfortunately, puzzle 66 was solved by

1Jvv4yWkE9MhbuwGUoqFYzDjRVQHaLWuJd (not us)

but got stolen using RBF. Puzzles 67 and 68 were solved by 1 person and then finally we were able to solve puzzle 69.


We are using our custom software written using CUDA C++. Each member has several GPUs which will be given a range to scan. It was really a eureka moment when we were notified that a match was found by one of our members.

We are aware of RBF attack so we used a wallet software (we prefer not to say which one) which does not enable RBF by default, to transfer the coins. But when we checked the transaction, before it was confirmed, another transaction was created.

This is really heartbreaking for me and my group because we spent months scanning the range only for it to be stolen by others. We are contributing part of our savings to pay our GPU bills monthly. We might resort to contacting the wallet software provider but we know that our 6.9 BTC is long gone forever.

Now, our problem is how to pay our remaining GPU bill which amounts to $158,954.07. This is so frustrating! Why can't people play fair and square???

We are accepting donations to help us pay our remaining GPU bill in these addresses:

Nice to see the bots battling it out for 69.
Did anyone even get close? I scanned 101C76FE and 101E4D0B...

The next puzzle is even harder. Good luck everyone.
